Terror seems to be no emergency to the authors of a new city emergency pamphlet – they say that instead of dialing 911, New Yorkers should dial 311, the city’s non-emergency hot line, if they have information about terrorist threats.

A Police Department spokesman was puzzled by the 311 recommendation, saying he thought the number was for quality-of-life complaints.

And the city’s Web site says the main purpose of 311 is to report loud noises, street-light outages or to learn if alternate-side parking is in effect.

The new use for 311 was announced yesterday by Mayor Bloomberg when he hailed the printing of nearly 600,000 copies of a 16-page pamphlet titled “Ready New York,” aimed at preparing households for emergencies – both natural and terrorism-related.

“If you have information about potential terrorism, call 311,” the pamphlet says on Page 11.

Emergency Management Commissioner John Odermatt praised the mayor for the “one-stop shopping” approach of 311.

Mayoral aides and city officials pointed out that once 311 operators identify a call as urgent, they can push a “panic button” that instantaneously transfers the call to 911, the city’s emergency phone number.

On the NYPD Web site, viewers are instructed to dial a third number, (888) NYC-SAFE, for terrorism-related calls.

As for the pamphlet itself, some of the recommendations include:

* If you are in a building collapse or explosion, “Get out as quickly and calmly as possible.” If you get out of the building, the pamphlet continues, “Get under a sturdy table or desk.”

* For hazardous material or chemical spills, the first guideline is to “stay upwind of the material if possible.”

* If you receive a suspicious package, “PUT IT DOWN – preferably on a stable surface.”

City Hall staffers hailed the campaign – which is almost entirely funded by the Sloan Foundation – as evidence that Bloomberg remains focused on the considerable dangers facing New Yorkers every day.

“The mayor works every day to keep New York City the most prepared and safest city in America,” said Vincent La Padula, a senior adviser to Bloomberg.
